Manumission of Slaves

Bukhari :: Book 3 :: Volume 46 :: Hadith 701

Narrated Ibn 'Umar:

The Prophet said, "He who manumits his share of a slave and has
money sufficient to free the remaining portion of that slave's
price (justly estimated) then he should manumit him (by giving the
rest of his price to the other co-owners)." Nafi' added, "Otherwise
the slave is partially free." Aiyub is not sure whether the last
statement was said by Nafi' or it was a part of the Hadith.
